Welcome to CompASS tool

This web interface allows the users to compare the secondary structure elements in the given two states of the same protein.

You just need to provide the 3D coordinates (pdb file) of the two states of protein and give name to the states for convenience. The assignment of secondary structure is performed by STRIDE (Structural identification), an algorithm that assigns protein secondary structure elements given the atomic coordinates.

We require coordinates of the two states of protein


You can give a name to the states (upto 10 characters) or let the tool use default names.

First state,

Name :

Copy and paste the atomic coordinates of the first state of protein.

Second state,

Name :

Copy and paste the atomic coordinates of the second state of protein.
